Śrīmad-Bhāgavatam · Text 4.12.9
Who is speaking and story frame
तस्य प्रीतेन मनसा तां दत्त्वैडविडस्तत: ।
पश्यतोऽन्तर्दधे सोऽपि स्वपुरं प्रत्यपद्यत ॥ ९ ॥
tasya prītena manasā
tāṁ dattvaiḍaviḍas tataḥ
paśyato ’ntardadhe so ’pi
sva-puraṁ pratyapadyata
The son of Iḍaviḍā, Lord Kuvera, was very pleased, and happily he gave Dhruva Mahārāja the benediction he wanted. Thereafter he disappeared from Dhruva’s presence, and Dhruva Mahārāja returned to his capital city.
